Be it known that 1, WILLIAM F. SMITH, a

citizen of the United States,

Brooklyn, in the of New York,

residing at county of Kings and State have invented a certain new anduseful Improvement in Wire-Straighteners, of which the following is afull, clear,

concise,

This invention ers,

and exact description.

relates to wire straightenand has for its object the production of awire straightener which is adapted to be used with a'plurality of sizesof wire.

The features of this invention are the means for adjusting andmaintaining the parallelism of two separate sets of rollers, means forpositioning the wire to be straightened without changing the operatingadjustment 0 f the rollers, and other details and combinations of partsas will herepanying drawings in inafter more fully appear.

A second plate 30, upon which is mounted a plurality of rollers 31similar to rollers 16 and having V-shaped grooves in their perlpheries,is slidably mounted within the guides 6 and 9. Coiled springs 32,engaging P1118. 33 in the ends of the plate 30 and pins 34 in the base 5and guide 9, normally tend to separate the rollers 31 from the rollers16. The rollers 31 are in staggered relation to rollers 16 so that thewire in passing through will follow a wavy path.

In order to adjust the position of rollers 31 with respect to rollers16, to maintain the two sets of rollers parallel, and to maintainparallel movement of the rollers 31, wedge blocks 35 are slidablymounted in the guides 6 and 9 in such manner as to engage angularsurfaces 36 of the guides 6 and-9 and the sides of the plate 30. A rod37, one end of which is provided with right hand threads, and the otherwith left hand threads, engages threaded openings 38 in the wedge blocks35. To maintain the rod 37 in a definite position with respect to theplate 30 after rollers 31 have been set parallel to rollers 16, nuts 45are pinned to the rod 37 and rest against bifurcated lugs 46 on theplate 30. To lock the rod 37 in a definite position, a lock-nut 47 isprovided therefor immediately below the lower lug 46. To the lower endof the base 5 may be attached guide 50 having an opening 51 throughwhich the wire is led to the rollers. To place the wire in properposition to be straightened, the hand wheel 23 is backed up so as todisengage the plate 15, and the plate 15 then turned about the screw 18,after which the wire may be fed through of the guide 50 and between thetwo sets of rollers. The plate 15 may then be returned to its normalposition and the hand wheel 23 tightened u to maintain the plate 15 inposition. To a just the relative position of the two sets of rollers,the 47 is backed up and the rod 37 turned sufiiciently in the properdirection, after which the lock-nut 47 is again tightened. Movement oftherod 37 imparts an equal movement to the two wedge blocks 35, which inturn impart to the plate 30 a movement to or from the plate 15, which isparallel to its original position and to the plate 15.

What is claimed is:

1. A wire straightener comprising a base,

a fixed and a movable set of rollers supported on said base, wedgeblocks, and a threadon said base, a second plate carrying a set ofgrooved rollers slidably mounted in said guides, tensioning meansnormally tending to separate the two sets of rollers, wedge blocksslidably mounted in said guides, and a connecting link engaging saidblocks for adjusting the position of, said movable set of rollers withrespect to said fixed set.

4. A wire straightener comprising a base, two plates supported by saidbase, a set of grooved rollers mounted on each of said plates,bifurcated guides mounted on said base, one of'said plates being pivotedat one end and adapted to be held rigid at the other or to be movedabout its pivot point to admit a wire between said sets of rollersWithout changing the operating adjustment thereof, the otherof saidplates being slided on said base, tensioning means normally tending toseparate said sets of rollers,

Wedge blocks, and a threaded rod engaging said blocks for adjusting theposition of said movable set of rollers with respect to said fixed set.

6. A wirestraightener comprising a base, a fixed plate carrying a set ofgrooved rollers mounted on said base, bifurcated guides mounted on saidbase, a second plate carrying a set of grooved rollers slidably mountedin said guides, tensioning means normally tending to separate the twosets of rollers, wedge blocks slidably mounted in said guides, and athreaded rod engaging said blocks for imparting a parallel movement tosaid movable plate for adjusting the relative position of said rollers.

In Witness whereof, I hereunto subscribe my name this 17 day of April A.D., 1914.
